SPGN120312 LX11 SPGN — Tungaloy indexable insert for Turning

SPGN120312-QBN LX11 Tungaloy indexable insert designed as a square 90° insert for general turning applications, offering stability and edge life in moderate to demanding machining tasks

• Tungaloy LX11 carbide grade for edge stability
• QBN chipbreaker for improved chip control
• 1.2 mm corner radius for repeatable profiles
• Square 12 mm size, 90° cutting angle

High productivity through geometry and chip control

The square insert’s QBN chipbreaker is engineered to maintain stable chip formation under interrupted cuts and varying feed rates. This geometry reduces the risk of built-up edge and supports consistent surface quality during series production. By combining a controlled chip path with a 1.2 mm corner radius, the insert ensures dimensional reliability and reduces rework. For process planners, this translates into fewer tool changes and improved cycle-time predictability, which supports leaner throughput and lower per-piece machining costs.

Carbide grade focused on balance between wear resistance and toughness

The LX11 grade from Tungaloy brings a considered compromise between wear resistance and fracture toughness. The substrate material is carbide, selected to withstand abrasive wear while retaining sufficient edge strength for transient loads. In practice, this means longer intervals between indexings and fewer scrapped parts from unexpected edge chipping. The technical composition of the grade suits operations where sustained surface finish and reproducible tool life are decisive selection criteria.

Robust form and dimensions for versatile turning use

The insert is square with a 90° cutting angle, a 12 mm size and a 3.18 mm plate thickness, offering mechanical stability in typical turning toolholders. The absence of a centre hole simplifies mounting in specific proprietary clamping systems and reduces potential stress concentrators. These dimensional features combine to deliver a stiff cutting edge: beneficial in both roughing passes that remove larger volumes and in finishing passes that demand repeatable form accuracy.

System compatibility and handling benefits

Packed as part of a modular system that includes the indexable insert, the matching insert pocket and fastening screws, this component integrates into common toolholders for turning operations. The square form and standard 120312 ISO designation make it straightforward to identify replacements and to plan inventory. Careful handling and correct torque when seating the insert ensure consistent contact and heat dissipation in the cutter body, contributing to longer, more predictable tool life.

FAQ

What does the designation SPGN120312-QBN mean for tool selection?
The designation identifies a square indexable insert with the ISO code 120312, a QBN chipbreaker and the geometry suited for standard turning fixtures, helping to match the correct insert to the holder.

Which materials are best suited for this insert grade?
The LX11 Tungaloy grade and carbide substrate are selected to balance wear resistance and toughness, making the insert suitable for a wide range of steels and industrial turning tasks where edge stability is required.

How does the 1.2 mm corner radius affect machining results?
A 1.2 mm corner radius provides a robust cutting edge that reduces the risk of edge chipping and supports consistent profile accuracy, especially useful in semi-finishing and general-purpose turning.

Is this insert compatible with standard square turning holders?
Yes, the square form and the 120312 ISO designation make the insert compatible with common square insert toolholders designed for 90° cutting geometries.

Are there recommended handling or seating practices for best performance?
Correct seating with the manufacturer-recommended torque and clean contact faces are essential; consistent clamping ensures reliable heat transfer and repeatable cutting-edge positioning for prolonged tool life.
